I would like to hire an Architect

We are looking to build a traditional square-style Japanese home with a courtyard in the center. We would like something approx. 2,000-ish square feet total, 4 bedrooms, large master onsuite, open concept with a modern flair. It is a very unique design and because of this we haven't picked out the land yet because we want an Architects insights. We are pre-approved for up to 400,000 dollars for the whole project at the moment, the price may increase as we save for a larger down payment over the next year.
